What is the diameter of 18cm to inches?
18cm is about 7 inches
The diameter equals 18cm how do I find the area?
The general equation for the area of a circle is π*r2, where r is the radius of the circle, and π is pi, which is approximately 3.14159. The diameter of a circle is how far it is from one side of the circle to the other, and the radius is how far it is the from edge to the center, thus the radius is half the diameter. Therefore the area is π*(92) ~ 254.47
What is the area of a circle with an 18cm diameter?
A = 254.47 cm2
Calculating radius and diameter?
Radius = Diameter/2 Diameter = 2* Radius
What is the Diameter to a radius of a circle?
A radius is one half of a diameter so divide by two to get from a diameter to a radius. Or you can multiply the radius by 2 to get to the diameter.
What is the radius with a circle with a diameter of 18cm?
9 cm (r = d/2)
If a circle has a radius of 9 cm how long is the circle's diameter?
The diameter is always double the radius so in this case, it is 18cm

What is the area of a circle if the radius is 18cm?
Using 3.14 as Pi the area of circle is: 1017.36
What is the area of a circle that has a radius of 18cm?
1,017.9 cm2
What is the area of a circle with an 18cm diameter?
A = 254.47 cm2
What is the circumference of a circle with diameter 18cm?
18 pi cm
What is the mass of solid iron wrecking ball with a radius of 18cm?
190kg
Calculating radius and diameter?
Radius = Diameter/2 Diameter = 2* Radius
How do you get the diameter from the radius?
to get the diameter from the radius you simply multiply the radius by 2 since the radius is half the diameter. d=2r where d = diameter and r = radius
